I'm very disappointed with Optima batteries. I will never buy another Optima. I have a yellow top in my garage that won't hold a charge. Supposedly you're supposed to hit them with a 100A charge a few times to bring them back. Suuuuuuuuuuuuure.
Good to know about Costco batteries. I'll have to pick up a couple for one of our trucks soon.

I've heard of that but if they won't hold a charge probably won't help. Good to know about Costco batteries even though I have a Sam's club membership. Good info.......Reps if I can.....

And for the cost of one battery?

And when I hook it up to the truck, she cranks so much faster with the higher reserve. Can I give reps to Xtreme?
Sorry to derail a bit. Just wanted to share some battery tech I learned....

If it was just one vehicle i would think different but all three do about the same and it's always one battery that goes bad
The set in my truck now are almost 2 yrs old but it's average milage is less than 200 a month,so I may get 2+ years out of these
The good is I've only had to buy 2 sets if batteries in almost 10 years

I have brought back two Optimas so far with my Xtreme charger. The pulse charging is what brings them back. Forcing an overcharge only overheats them and burns them out. I have also brought back Diehards and Motorcrafts with this charger. I love it.

I have done this about once a month for the year that I have had the Xtreme and very happy with the results.
You can leave it hooked to both batteries in parallel but it takes longer to work.
If any vehicle at my place gets parked for more than a few days, the Xtreme goes on it and the battery is always good when the vehicle is started. The Cherokee in the backyard has been parked for about a year, but still starts since I put the Xtreme on it every couple months.
The instructions with the Xtreme say you can use it as a "trickle" charger, and it will pulse your battery at low levels while on "trickle", helping maintain charge and battery conditioning.

Yeah, exactly. It looks like a battery tender. I can keep it charge when constantly trickling it. If it's not on a charger, it's dead.

I do not know who "Batteries Are Us" is. I bought the Xtreme a year ago and have seen first hand what it has done.
I also have a 200+ amp starting charger that can blast a battery into thermonuclear overload in seconds.
The Xtreme does a better job.

And upon reading the Batteries Are Us info, I can agree on some of it.
The two dead Optimas I brought back, did get blasted with 200 amps until they got warm, allowed to cool, blasted again, allowed to cool, and then put on the Xtreme. I never allowed them to get hot.
Any battery overheated is only worth recycling.

The Xtreme works on deep cycle and regular batteries.
Works on ALL my batteries, even the 12v batteries for my Makita drill.
Damn, now I sound like a salesman.
